ISO, the International Standards Organization maintains a WWW site at http://www.iso.ch/

ISO 233:1984

  Documentation - Transliteration of Arabic characters into Latin characters.

ISO 233-2:1993

  Information and documentation - Transliteration of Arabic characters into Latin characters - Part 2: Arabic language - Simplified transliteration.

ISO 639:1988

ISO 8859-6:1987 (ASMO 449E)

  Information processing -   8-Bit single-byte coded graphic character sets - Part 6: Latin/Arabic alphabet.

This is an 8-bit code closely related both to 7-bit ASCII and to ASMO 449; whereas the lower 128 positions are identical to ASCII (ISO 646), the upper 128 positions contain the Arabic characters of ASMO 449 in the analogous places, plus a few additional graphic and control characters. The file ISO-8859-6.ps at ~reader/coding-sets is a Postscript sheet for the Right-Hand part of ISO 8859-6.

More information about the ISO 8859 Series can be found at http://www.cs.tu-berlin.de/~czyborra/charsets/

ISO 9036:1987 (ASMO 449)

  Information processing -   Arabic 7-bit coded character set for information interchange.

This is the standard adopted by the Arab Standards and Metrology Organization (ASMO) in 1985. It is a 7-bit code, differing from ASCII mainly by replacing the letters by the Arabic letter characters and diacritical marks; the Arabic digits share their positions with the ASCII digits. The positions of special and control characters in both codes are identical. The file ISO-9036.ps at ~reader/coding-sets is a Postscript sheet for ISO 9036.

ISO/DIS 11822

  Information and documentation - Extension of the Arabic alphabet coded character set for bibliographic information interchange.

Unicode

  is a 16-bit code. See http://unicode.org/ or http://www.stonehand.com/ for more information about Unicode. The directory unicode and its subdirectories at ~reader/text have also some information about unicode.
